United States Patent 3,215,328 CONTAINER BODY AND METHOD F PRODUCING THESAME Arthur John White, Woodbury, N.Y., assignor to American CanCompany, New York, N.Y., a corporation of New Jersey Filed Dec. 7, 1962,Ser. No. 242,976 2 Claims. (Cl. 229-45) This invention relates to acontainer body and to the method of producing the same and hasparticular reference to a spirally wound fibre container body having anarrow band or strip interposed between the overlapped edges of theregular spirally wound label on the container body to provide asupplemental label which is particularly adapted for displayinginformation relating to temporary promotional compaigns.

In an effort to further promote the sale of merchandise packaged incontainers, many companies run promotional campaigns from time to time,granting price discounts or making other special offers designed toinduce the purchaser to buy the merchandise. In many instances, thesecompanies desire to include information relating to these special offersdirectly on the package. Normally, this requires a change to the regularcontainer label, thus necessitating a complete new set of printingplates to make the altered label.

As alternatives, the regular label is used, and the promotionalinformation is either printed directly on one of the end members of thecontainer, or is contained in a separate label which is afiixed to oneof the container end members. Such procedures add considerably to thecost of the container, and are not effective when the container isdisplayed in such manner that its body label is presented to theconsumer.

The present invention overcomes these problems by providing a spirallywound container body construction wherein the regular spirally woundlabel is used, and wherein a separate narrow supplemental label bandmade of a suitable label material such as paper, cellophane,

` foil label stock or the like and containing the temporary advertisingmaterial is secured to the container body in such a manner so that it isinterposed between the helically overlapped edges of the regular labeland extends outwardly beyond the lapped marginal edge portions of theregular label, thus providing an eye-catching advertising device.

This supplemental label is secured to the body during Vthe regularspiral winding operation and its addition requires no substantialchanges in the regular body making procedures other than the minimum ofequipment necessary to guide the supplemental label to the winding man-Hence, the supplemental labels may be added or discontinued at will, andat minimum expense. In addition, they are securely attached to the bodyso that they cannot be detached by storekeepers to whom the packages aresold at a reduced price for resalel at a reduced price, and who mightdesire to delete the temporary advertising and sell the packages at theregular price as regular merchandise.

An object of the invention therefore isV the provision of a containerbody having a regular spirally wound label which covers substantiallythe entire exterior surface of the container body and having a narrowsupplemental label which extends helically around the body and issecured thereto to prevent surreptitious detachment.

Another object is the provision of a supplemental label which may beadded to a container body to augment the regular body label at a minimumof expense.

A further object is the provision of a supplement label which containsan easily detachable premium coupon.

"ice

A still further object is the provision of a method of manufacturing aspirally wound container body incorporating a supplemental label whichsatisfies some or all of the previous objects of the invention.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

Referring to the drawings:

FIGURE 1 is a perspective view of a container having a spirally woundfibre container body provided with a supplemental label which extendsoutwardly from between the lapped edges of the regular body label;

FIG. 2 is an enlarged sectional view through the body of the container,taken substantially along the line 2 2 of FIGURE 1; and

FIG. 3 is a schematic view illustrating the instant method of making thefibre container body shown in FIG. 1.

As a preferred and exemplary embodiment of the instant invention, FIG. 1of the drawings discloses a cornpletely sealed container 11 formed witha multi-ply lspirally wound body 12 having an outer spirally wound layeror ply 13 which comprises a regular or standard label which completelycovers the exterior surface of the main body 12. The opposite ends ofthe body 12 are closed and sealed by top and bottom metal end members14, 15 which are secured thereto in liquid-tight end seams 16 which maybe single, crimped seams or interfolded double seams. i

The body portion 12 of the container also includes inner and an outerhelically wound main body plies 17, 18 which are glued together and arecomposed of relatively tough fibre body stock such as kraft, chipboardor the like to provide adequate strength to the container. The edges ofthe main body plies 17, 18 preferably are disposed inbutt joints 21, 22,respectively, which are arranged in offset relation, one from the other,as best shown in FIG. 2.

The body 12 of the container is protected by the outer label layer 13which completely covers the underlying main body ply 18 to make thecontainer moisture and water resistant, thus preventing deterioration ofthe body 12 in the event the container is exposed to water or dampnessduring storage. For this purpose the label ply 13 may comprise a thinlayer of aluminum foil 23 which is prelaminated to a supporting kraftpaper backing 24. The longitudinal, helically disposed edges of thelabel ply 13 preferably are overlapped in what may be designated as alap joint 25 to more completely protect the underlying main body plies17, 18 against the penetration of external water and moisture.

The interior surface of the inner main body ply 17 of the container body12 may if desired be lined with a spirally wound liquid proof liner ply(not shown) or sprayed, coated, covered or treated in any other suitablemanner to render it liquid, moisture and grease proof. Since thetreatment or covering of this surface forms no part of the instantinvention, no further explanation is believed necessary.

The label ply 13 preferably is -of the conventional type which ispreprinted with an individual decorative label pattern.

When a company wishes to offer a temporary price discount @or otherspecial inducement to purchase its products, it frequently ydesires toprovide additional information somewhere Ion the container 12 informingthe purchasing public of its offer.

In order to make it possible to provide such infonmation withoutnecessitating the use of a complete new set of printing plates, as wouldbe necessary if the regular label pattern were to be changed to addinformation about wound thereon.

the special offer, a supplemental label 26 in the form of a relativelynarrow web or strip is provided.

The supplemental label 26 may be formed of any suitable material, suchas paper, cellophane -or other plastic, paper-backed foil, plain foil,or the like. If desired, a clear cellophane or similar plastic materialmay be utilized so that the main portion of the regular label will not'be obscured by the supplemental label 26 except for the printed ymatterappearing thereon. Usually, however, it is desirable to have t-hesupplemental label 26 contrast sharplywith the regular label 13.

The supplemental label 26 is applied to the container lbody i12 in suchmanner that a longitudinally extending marginal -edge -portion 27 of thesupplemental label 26 is interposed between the lapped helical edges ofthe regular label .13 at the lap joint (see FIG. 2).

The supplemental label 26 is glued to the underside of t-he overlappededge portion of the main label ply 13, preferably by an adhesive 28which is applied to the underside of the main label ply 13 during theformation of the container, body, as will hereinafter be described.

This -glue bond serves to hold t-he supplemental label 26 securely inplace so that it cannot be wholly detached yfrom the `container exceptby the obvious destruction of the overlapped edge of the main label ply13. In addition, the inward pressure exerted by the overlying edgeportion of the main label ply |13 tends to hold the supplemental label26 in place, as does the fact that the supplemental label 26 extendshelically around t-he body 1'1 for its -full height, from its top to itsbottom edge, so that its ends are incorporated in the end seams 16 andanchored in 'place thereby.

The balance, or remaining longitudinally extending portion 29 of thesupplemental label 26 projects outwardly from the lap joint 2S andcontains the printed indicia or supplemental label legend, generallyindicated by the numeral 30, which is exposed to view.

If it -is desired to incorporate a premium coupon 31 in the exposedportion '29, this is easily done by outlining the coupon 31 with asubstantially U-shaped line of weakening such as a score -line or lineof perforations 32, both ends of which terminate at the exposedlongitudinal edge of the supplemental label 26. Because the exposedporftion 29 is not normally glued down, the coupon 31 may be readilydetached from the supplemental label 26 by ytearing the latter along theline of weakening 32.

The supplemental label 26 preferably is applied to the container body1.1 at the time the regular label 13 is Normally, these operations takeplace substantially simultaneously Wit-h and as an integral part of thebody forming operation.

The preferred method of forming the container body f1|1 is disclosed inFIG. 3 of the drawings. lIn this method, the container body .1,2 isyformed on a stationary mandrel 33 which is anchored securely at one endin a rigid block '34. The other end -of the mandrel 33 is free to permitdischarge `of the AWound tube from which the individualcontainer'lbodies 12 are cut.

In making a body 12 constructed as shown in FIG. 2, the inner main bodyply 17 is rst wound onto the mandrel 33 at a .point adjacent the block34. This inner .imain 'body ply 17 preferably is wound with its leadingedge abutted against its trailing edge to formnthe butt joint 21 (FIG.2). A continuous overall film yof a su-itable adhesive preferably isapplied to the outer sur- -face of the ply 17 in any suitable manner, asby -a glue applying roll 36, as this ply 1'7 is fed toward the mandrel33 4 relation of the butt joints 21, 22 of the respective inner and4outer main body plies 17, 18, the ply y18 preferably is wound on theply 17 so that the longitudinal edges of the ply 18 are out of alignmentwith the corresponding edges of the ply 17.

The winding of the inner and outer plies 17, 18, as just described,forms them into a continuous tube 36 lwhich advances toward and passesbeneath an endless winding belt 37. This belt 37 operates around adriving drum 38, disposed and driven in any suitable manner at yone sideof the mandrel 33, and ,an idler drum 3-9 located in spaced relationfrom the driving drum 38 at the opposite side of the mandrel 33. Aportion .of the belt 37 intermediate the drums 38, 39 is looped aroundthe mandrel 33 Yin tight driving engagement with the tube 36 to advanceit helically along the mandrel 33 in order to pull the inner and outermain body plies 17, 18 which comprise the tube 36 from their respectivesupply rolls (not shown).

After the tube 36 passes through the loop of the winding belt 37 in itsadvancement along the mandrel 33, it moves into position for receivingthe main or regular label ply .13. This regular label ply 13 preferablyis slightly wider in its transverse dimension than that of the bodyplies .17, 18 to provide the overlap which creates the Ilap joint 25(FIG. 2). The label ply 13, with the paper layer 124 prelaminated to thefoil 23, is fed in- Wardly from one side of the mandrel 33 onto the bodytube 36 (FIG. 3).

The whole of t-he inner surface of the paper layer 24 of the label plyy13 is provided with an overall coating of the adhesive 28 as it passesover an adhesive applying roller 40. Hence, as the main llabel ply 13 ishelically wound onto the tube 36 it is adhesively secured to the 'outermain body ply 18.

The label ply 13 preferably is printed with complete unitary labeldesigns which are printed at an angle to its longitudinal edges andseparated from each other at `fthe lines 41. These label designs are solaid out that when the label is Wound onto the tabs, each label designconstitutes a regular or standard label pattern. As a result, afterwinding, the tube 36 is completely covered by the label ply y13 whichcontains a succession of labels which provide a decorative andprotective outer covering thereon.

During the winding operation just described, thel supplemental label 26is fed onto the mandrel 33 in such manner that its edge portion 27 iscaught between and covered by the successive convolutions of the labelply 13. For this purpose, the band 27, having all the specialpromotional matter arranged and preprinted on its edge portion 29 whichis not covered by the regular label 13, is fed at the same winding angleas are the other container plys 13, 17, 18, with its printed portion 29positioned rearwardly of the trailing edge of the label ply 13 (FIG. 3).As a result, the portion 27 of the supplemental label 26 is caughtbetween and overlapped by the trailing edge portion of the regular labelply 13, while the portion 29 is not, but instead extends outwardly fromthe lap joint 25` If it is desired to provide the coupon 31, the line ofweakening 32 is provided in the supplemental label 26 prior to the timeit is fed onto the mandrel 33. This preferably is done as an incident tothe printing of the indicia 30.

The winding operations just described result in the formation of anished tube designated by the numeral 42. As the finished tube 42gradually moves toward and off the free end of the mandrel 31 it is cutalong the spaced lines 41 to divide it into individual container bodies12. Thereafter, a bottom end 15 is secured onto the bottom end of eachcontainer body 12, the container filled with a product, and top end 14'seamed onto the other end of the body 12 to create the finished package.

It will be realized that various modifications of the instant containerbody construction may be made withoiit departing from the scope of theinstant invention. For example, the portion 27 of the supplemental label26 may be extended inwardly beyond the edge of the underlapped portionof the main label ply 13 so that itcomes into contact with the outersurface of the outer main body 1S to thus more securely attach thesupplementary label 26 to the body. If this is done, it may be desirableto coat the inner surface of the covered portion 27 of the supplementallabel 26 with an adhesive so that it is glued down, and thus preventinadvertent peeling of the supplemental label 26 and main label ply 13in the area of the lap joint 25. In addition, if it is desired toincrease the width of the exposed portion 29 of the supplemental label26, it may be desirable to provide a narrow stripe of Iadhesive on itsunderside, adjacent its outer edge, to tack it down against the body.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description and it will beapparent that various changes may be made in the form, construction,yand arrangement of the parts and that changes may be made in the stepsof the method described and their order of accomplishment withoutdeparting from the spirit and scope of the invention or sacricing all ofits material advantages, the form hereinbefore described being merely apreferred embodiment thereof.
